MoWSe2 (Molybdenum Tungsten Diselenide alloy)
MoWSe2 alloy is a semiconductor. We have many different types of MoWSe2 alloys available containing a different ratio Mo/W: ranging from alloys which are rich in Tungsten (close to 2H-WSe2) to alloys with a high Molybdenum content (close to 2H-MoSe2). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Molybdenum Tungsten Diselenide alloy belongs to the group-VI transition metal dichalcogenides (TMDC).
